The girls' mom was recording and the video went viral, with millions of views. Even Ellen DeGeneres took notice and posted it saying, “Their sister was sick, so this doctor cheered them up with a dance. I love this."

Matthew dispenses medicine in the form of laughter, connecting with tiny patients, some of whom never make it home.

“I’ve gone to a bunch of funerals for my kids and some people tell me, 'Chima, you get too close you know, don’t let your heart get in it. 'I am ready to walk away from medicine the day my heart is not in it,” he said.

A feeling shared by the sisters, with the doctor who danced his way in their hearts.

Matthew was so inspired by his patients he is starting his own foundation to help children beyond the hospital doors.
